Plastic product surface



FIG. 1 is a top plan view of our new design for plastic product surface;

FIG. 2 is an enlarged, partial view thereof; and,

FIG. 3 is a perspective view of an enlarged fragment of the design in condition of use on a broken line bag. The broken line showing of environmental structure in this view forms no part of the claimed design.

The broken line border surrounding the claimed design indicates that a specific length and width of plastic product surface forms no part of the claimed design. The repeating pattern is understood to repeat uniformly throughout the length and width of the claimed design. 

The ornamental design for a plastic product surface, as shown and described.
